Vedclass · Answer

(B) The boiling point depends on the extent of intermolecular hydrogen bonding.$H_{2}O$ has the highest boiling point because each molecule can form four hydrogen bonds due to the presence of two hydrogen atoms and two lone pairs on the oxygen atom.$HF$ has a high boiling point due to strong hydrogen bonding,but it forms fewer hydrogen bonds per molecule compared to $H_{2}O$.$NH_{3}$ has the lowest boiling point among these three because nitrogen is less electronegative than oxygen and fluorine,resulting in weaker hydrogen bonding.Therefore,the correct order is $H_{2}O > HF > NH_{3}$.
